Abstract

Solubility diagram for complex aqueous system containing ammonium chloroethylphosphonates, ammonium phosphate, ammonium sulfate, and sodium tricarbamide chlorate has been studied by visual polythermal method in the temperature range from –21 to +52°C. Polythermal phase diagram with demarcated fields for ice and components crystallization has been plotted. Formation of new compound, ammonium chloroethylphosphonate monochlorate NH₄ClO₃∙ClCH₂CH₂HPO₃NH₄, has been established; its composition was confirmed by chemical and physicochemical analysis. Viscosity, density (at 25°C), and crystallization temperature for a number of mixtures in [65%NaClO₃∙3CO(NH₂)₂ + 5%(NH₄)₂SO₄ + 30%H₂O]–[21%ClCH₂CH₂PO(OH)₂∙NH₃ + 11%ClCH₂CH₂PO(OH)₂∙2NH₃ + 12%NH₄H₂PO₄ + 56%H₂O] system have been studied.
